IMPROVEMENT IN CHURN-DASHES.

Specification forming part of Letters Patent No. 145,107, dated December2, 1873; application filed October 25, 1873.

To all whom it may concern:

Be it known that 1, ANDREW J. HUDsoN, of Camden, in the county of Bentonand State of Tennessee, have invented a new and useful Improvement inChurn-Dasher, of which the following is a specification:

. Figure l is a top view of my improved churndasher. Fig. 2 is a sideview of the same. Fig.3 is a cross-section of the same taken through theline .70 00, Fig. 2.

My invention has for its object to furnish an improved churn-dasher,simple in construction, inexpensive in manufacture, and effective inoperation, bringing the butter very quickly, and developing all thebutter that may be in the milk; and it consists in the dasher providedwith grooves or concaves, recesses, shoulders, and notches, ashereinafter more fully described.

Similar letters of reference indicate corresponding parts.

A represents the dasher, which is designed to be attached to a rotatingshaft, and driven by gearing in the ordinary manner. The dasher A ismade in the form of a two-armed bar, and is attached at its center tothe rotating shaft, as indicated by the hole in the center of saiddasher. Upon the upper side of one arm of this dasher A is formed arounded, hollow, or concave groove, to, inclining outward and upward,and in the under side of the other arm is formed a similar groove, a,inclining outward and downward. Upon the under side of one arm of thedasher A, below the groove a, and upon the upper for the purpose setforth.

side of the other arm of said dasher A, above the other groove, a isformed a recess, a, having a convex bottom and vertical sides. The outershoulder, a of the recess a", is curved, and extends from the forwardside of the dasher-arm to about the center of the rear side of said arm,where it terminates in a notch, a. The forward part of the innershoulder, c ,is inclined, as shown in Fig. 1,and is vertical, as shownin Fig. 2, and its rear part is at right angles with the length of thedasher A, as shown in Fig. 1, and is inclined or curved laterally, asshown in Fig. 2; By this construction the dasher, in its movement,throws the milk in currents in different directions, which currentscollide with each other and with the sides of the churn, throwing themilk into violent agitation, bringing the butter in a very short timeand developing all the butter there may be in the milk, thus prodncingbetter and more butter than an ordinary dasher.

Having thus described my invention, I claim as new and desire to secureby Letters Patentconcaves a the recesses a the shoulders at and a andthe notches a, constructed and arranged in connection with each othersubstantially as herein shown and described, and
